motor shaft, back side first. Note that
the back side of the prop is the side
that has no writing on it.

Add the prop washer, then the
nut as shown in Figure 21. Note that
the NTM motors have a spinner
instead of a nut. Tighten the
nut/spinner.

Not all your props are the same.
Two of them are left turning props
and two are right turning props. The
props marked with the R should be
installed on motors 2 and 4. If the
prop nomenclature does not have an
R, it is assumed to be left turning, and
should be installed on motors 1 and
3. Refer again to Figure 8 for the
motor numbers.

Conclusion

So, you have gone
through four months of
gathering parts and
assembly. You want to
actually get your Kronos
Flyer soaring. This is
difficult to cover in an
article, so I uploaded a
video to both my website
and at the article link.

UNM

I own several craft
that I have built, and
while the cost of the
frame components, ESCs,
motors, and hardware
can add up, they are
nowhere near the cost of
a NAZA flight controller --
especially if you have
purchased the GPS
upgrade. For this reason, I created the Universal NAZA
Mount (UNM).

Your NAZA, VU, receiver, and (optional) GPS mount
onto the UNM platform. The UNM platform mounts to
your components platform. The only external connections
are the VU power and the four ESC connections. This
allows you to move the NAZA and radio to another craft
with little effort. It only takes a couple of minutes.

Shown in Figure 22, the UNM is held in place by four
acorn nuts that attach to the four inner screws on your
component platform.

More information on the UNM can be found on my
web site at
www.kronosrobotics.com.

Next Month

Next month, I will close out this series. I will go over
upgrade options and some of my future plans for the
Kronos Flyer.
